This is a fun work of fluffy fiction, not to be taken too seriously and I really like it. Do we even know if the character of Amy is an actual angel? No! She could just be a good hearted nut case. It hasn't been revealed and leaves it to your imagination...so far, anyway. The show doesn't have a heavy religious message, so after a hard day's work, it's just what you need to relax to. The show is funny, enjoyable and who doesn't love Jayne Lynch?! She's fantastic, bringing likability, humor and a bit of chaos to the part quite well! Through all her mildly annoying traits, she still manages to be helpful and kindhearted, so if there were a real message, I'd say that would be it!
